Water vapour is one of the major components in the atmosphere with strong impacts on the earth's climate and weather. Water vapour absorbs radiation in the infrared spectral range and its abundance in the atmosphere, making it the most important natural greenhouse gas.
The Total Column Water Vapour (TCWV) generated by S5P-PAL is a pre-operational TROPOMI product. In contrast to other satellite sensors, TROPOMI provides daily global measurements of TCWV over land and ocean.
The TCWV processor is developed and maintained by DLR.
All users are encouraged to first look at the README file for a general description on how to use the TCWV product.

The dataset does not provide a full timeline and products for several orbits are known to be missing. Information about known acquisition gaps in the data can be found on the Mission Status webpage of Sentinel-5P.
The currently published TCWV products have an error in their footprint metadata field: the longitude/latitude order is flipped.
Available product files can be selected and downloaded using the SpatioTemporal Asset Catalog (STAC) browser interface.
